W. Dawson, Laurie L. Bloomfield, Isabelle Charrier, and Christopher B. Sturdy University of Alberta Both black-capped (Poecile atricapillus) and mountain chickadees (Poecile gambeli) produce a chick- a-dee call that consists of several distinct note types. In some regions, these 2 species live sympatrically, and it has been shown that 1 species will respond weakly to songs of the other. This suggests that chickadee song, and potentially other of their vocalizations, contains species-specific information. We tested the possibility that call notes were acoustically sufficient for species identification. Black-capped and mountain non-D notes were summarized as a set of 9 features and then analyzed by linear discriminant analysis. Linear discriminant analysis was able to use these notes to identify species with 100% accuracy. We repeated this approach, but with black-capped and mountain D notes that were summarized as a set of 4 features. Linear discriminant analysis was able to use these notes to identify species with 94% accuracy. This demonstrates that any of the note types in these chickadee calls possesses sufficient information for species classification.

Nest Boxes for Native Cavity Nesting Birds”
Ecology Technical Bulletin, Number 1 “Nest Boxes for Native Cavity Nesting Birds” Populations of native cavity nesting birds have been in long-term decline throughout New York State, and across the country. Loss of suitable nesting sites and competition from non-native birds are the major factors in these population declines. The New York State Department of Transportation (NYSDOT), through it’s ownership of approximately 1% of New York State, has the potential to enhance nesting opportunities for native cavity nesting birds by the well-thought-out placement of nest boxes. However, it is critical that the decision to place nest boxes be carefully planned so that boxes are of the appropriate type, placed in suitable habitat and are monitored on a regular basis during the nesting season. Failure to consider these factors will result in enhancing nesting opportunities for non-native birds and thus further the plight of our native species. This bulletin will provide basic information and recommendations regarding the proper use of nest boxes on and adjacent to NYSDOT property. For more information, please refer to the references at the bottom on this document. Eastern Bluebird (Sialia sialis) New York’s official state bird, the Eastern Bluebird, historically nested in suitable natural cavities (holes or hollows in trees or wooden fence posts) or cavities excavated by other bird species that offer protection from predators, competitors and the elements. In addition, these nest sites had to be the correct size and needed to be located in the appropriate habitat for bluebirds, i.e. short-grass fields or large mowed areas with scattered shrubs for perching. -

Attracting Bluebirds 1.Mount Nest Boxes
Bluebirds A gentle bird with brilliant blue plumage, the bluebird has endeared itself to people across the country. Bluebird populations, like many other birds, have declined over the last century due primarily to loss of habitat caused by development. Bluebirds nest in tree cavities, and the loss or destruction of old, decaying trees has reduced the availability of suitable nesting sites and increased competition with other cavity-nesting birds. Bluebird Natural History There are three species of bluebirds in North America: Eastern, Western, and Mountain. The various species differ mostly in territory and feather color. The males of all three species are brilliant blue on the head and back, with varying amounts of white and rust on their neck and breast. Female bluebirds are less bright, with more gray-brown coloring on the back and blue highlights on the wings and tail. Bluebirds feed on a large variety of insects, arthropods, and invertebrates, The Eastern bluebird is one of three species of bluebirds found in North including spiders, caterpillars, and grasshoppers. Bluebirds perch on posts, America. Bluebirds are cavity nesters, and can be attracted to your property wires, or branches while scanning for insects. Watch for the bluebird’s by installing nest boxes. characteristic behavior of flying down from its perch to catch prey and then returning to the original perch to eat. In winter, bluebirds are dependent upon berries to supplement their diet. Bluebirds prefer open habitats, such as meadows, parks, orchards, farm fields, and golf courses. They often spend the winter in woodlands or groves. Ranges Eastern Bluebirds are in all states east of the Rockies, from southern Canada to the Gulf of Mexico. -

Ross LEIN~ Division of Ecology(Behavioral Ecology Group), Department of BiologicalSciences, University of Calgary, Calgary, Alberta T2N lN4, Canada Abstract. In an attempt to determine the factors permitting sympatry of Black-capped Chickadees (Parus atricapillus) and Mountain Chickadees (P. gambeli) in southwestern Alberta, we examined nest-site utilization and foraging behavior during the summers of 1982 to 1984. Characteristicsof both the nest tree itself, and the surroundinghabitat, differed significantlybetween nest sitesofthe two species.Patterns of reuseofnest sitesand behavioral observationssuggested that some interspecific competition for nest sites may occur, but is probably not important. Foraging behavior differed significantly between the two species, suggestingthat Black-cappedand Mountain chickadeesdo not compete for food during the breedingseason. Differences in habitat use by the two speciesapparently provide ecological segregation,and their coexistenceon our study area is due to the mosaic nature of the habitat.

Bird Houses for Cavity Nesting Songbirds – SW Oregon – Guidelines
Lee Webb, Wildlife Biologist 22 March 2002 Bird Houses for Cavity Nesting Songbirds – SW Oregon – Guidelines Nest Box Placement 1. Face box away from afternoon sun, nor should the prevailing wind blow into the opening. 2. Correct height, but not so high the box can’t be checked or cleaned (see Table below). 3. Generally, nest boxes placed on the bare portion of a tree trunk or on a pole in the open have a better chance of being occupied than do boxes surrounded by vegetation. 4. The top of the box should not tip to the rear (backwards). Young birds might not be able to get out! 5. Boxes do not need perches, which serve predators better than residents of the boxes. 6. Well-spaced-out boxes will receive more use than those clustered together. (Avoid inter- and intra-species territorial conflicts.) If possible, place boxes so that one cannot be seen from another. 7. Black-capped chickadee (conifer), White-breasted Nuthatch (conifer), Oak Titmouse (hardwood), and Ash-throated Flycatcher (hardwood) seem to favor nest boxes placed up into the lowest live limbs of the preferred tree type, a short distance (perhaps 1 to 3 feet) out from the bole, preferably not in densely vegetative limbs, but somewhat open.

Common Birds of the Estero Bay Area
Common Birds of the Estero Bay Area Jeremy Beaulieu Lisa Andreano Michael Walgren Introduction The following is a guide to the common birds of the Estero Bay Area. Brief descriptions are provided as well as active months and status listings. Photos are primarily courtesy of Greg Smith. Species are arranged by family according to the Sibley Guide to Birds (2000). Gaviidae Red-throated Loon Gavia stellata Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: A small loon seldom seen far from salt water. In the non-breeding season they have a grey face and red throat. They have a long slender dark bill and white speckling on their dark back. Information: These birds are winter residents to the Central Coast. Wintering Red- throated Loons can gather in large numbers in Morro Bay if food is abundant. They are common on salt water of all depths but frequently forage in shallow bays and estuaries rather than far out at sea. Because their legs are located so far back, loons have difficulty walking on land and are rarely found far from water. Most loons must paddle furiously across the surface of the water before becoming airborne, but these small loons can practically spring directly into the air from land, a useful ability on its artic tundra breeding grounds. Pacific Loon Gavia pacifica Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: The Pacific Loon has a shorter neck than the Red-throated Loon. The bill is very straight and the head is very smoothly rounded. -

We documented the highest vertebrate scavenger diversity of any study to date (39 birds and mammals). Scavengers represented 10.9% of local birds and 28.3% of local mammals, emphasizing the diversity of food-web vectors supported by pumas, and the positive contributions of pumas and potentially other subordinate, apex felids to ecological stability. Scavenger diversity at carcasses was most influenced by the length of time the carcass was sampled, and the biological variables, temperature and prey weight. Nevertheless, diversity was relatively consistent across carcasses. We also identified six additional stalk- and-ambush carnivores weighing > 20 kg, that feed on prey larger than themselves, and are subordinate to other predators. Together with pumas, these seven felids may provide distinctive ecological functions through their disproportionate production of carrion and subsequent contributions to biodiversity. -
